Off the line, the i4 eDrive35 hits 100 km/h in 6.08 s versus 6.15 s for the 125i. The instant torque of 400 Nm from the electric motor makes the difference. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the i4 eDrive35 is doing 131 km/h against 131 km/h for the 125i. The gap is 0.01 s. The gap remains stable from the start.
At 400 metres standing start, the 125i crosses the line in 14.35 s versus 14.38 s. The 0.02 s gap represents roughly 1 m of track
Past 400 metres, the 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 179 km/h. At 1,000 metres, the 125i finishes in 25.91 s versus 26.26 s, with a 0.35 s lead.
Both rivals are electronically governed, but not at the same level: the i4 eDrive35 is capped at 190 km/h, the 125i at 243 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.35 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i4 eDrive35 G26 and 125i F20LCI are neck and neck (6,08 s vs 6,15 s, no significant gap).
i4 eDrive35 G26 goes from 0 to 100 km/h in 6,08 seconds (calibrated simulation).
